Found the Solution - "Literally"

I wasn't about to give up on this that easily . I read a lot on the internet today while watching NASCAR qualifying and I found the solution. Now, there are two types of deposits on the pan. One is the dark black fat deposits. Those are the smaller black spots where fat has baked on. The second is a brown varnish like smoke deposit. Those were the biggest areas on the pictures I posted above,

Well, the brown varnish was gone almost instantly. I'm giving the baked on grease spots an hour and see how they do.

Here's the method.

Get a big plastic pan where you can submerge the whole stainless pan. I happened to have one. It's a kitty litter pan that I use to carry two-2.5 gallon chlorine jugs to the house from the pool supply store so that any spills don't ruin the car. Paid three dollars for it a long time ago. I then got water out of the tap as hot as I could get it - 160 degrees is my number there abouts. I added enough water to almost cover the Weber pan and then added about a quarter gallon of white vinegar. We keep gallon jugs of white vinegar around because my wife uses it on our tile floors (now I know why ). Next time I'll just do it in the kitchen sink.

The varnish disappeared in less than 3-minutes - zero scrubbing! I'm letting it sit to see if it will remove the burnt on grease. I will post the after pics tonight.

The results are in...

OK, an hour passed and I still had some black burned fat deposits. But, a very light, less than 30-second scrubbing with a yellow scrub pad took care of those instantly. I'm thinking that an hour wait might not be necessary. I just wanted to see if the burnt spots would go away on their own.

In all honestly, I did have some chemical stains from previous attempts at cleaning this thing (very dark big gray stains - those were unrelated to the cooking process and not present in the original pics) which I became aware of when all the other stuff magically disappeared, and those were removed while in the vinegar bath with 600 grit wet and dry in about a minute. DO NOT USE OVEN CLEANERS - they stain and darken the stainless. If you just wash the thing normally and then set it in the vinegar bath you'll be done before the rest of ther dishes go in the dishwasher!

So here are the after picks. If I had not used all the heavy chemicals first this whole thing would have taken less than 5-minutes of my time (not taking soak time into account, just prep). I'll take this small amount of work every day of the week ! Please refer to the before pictures in my post above to see the difference.
